The Postal Service offers lower prices for mail that is transported by the mailer to certain kinds of postal facilities. Generally, the closer you take the mail to its final destination, the less postage you pay. Why? Because the Postal Service doesn't have to transport the mail as far: you've already done some of the transportation work for us. That saves the Postal Service money—and the savings are passed on to you.

Some mailers who live near a large mail processing plant may be able to take advantage of these lower postage prices simply by driving a short distance to drop off their mail. Your business mail entry staff[5] can talk to you about your options.
